Add Cover Image

Adding a cover image makes your book list more visually appealing and easier to browse. The cover image field in the edit screen offers two ways to set an image.

Camera Capture / File Selection / Google Images (Recommended)

Tap the button next to the cover image field to open the image source selection screen.

  • Choose from files — Select an image saved on your device
  • Take a photo — Launch the camera to photograph the book cover
  • Search on Google Images — Open a Google Image Search with the book's title and author

The selected image is automatically resized. The storage location is determined by your connection status:

StatusStorageDetails
Google Drive connected Google Drive No impact on file size. Most reliable
PC + no Drive Local folder Saved alongside rfnote
Mobile + no Drive Inside file (base64) File size increases. Confirmation dialog shown

Using Google Image Search

When you select "Search on Google Images", a Google Image Search opens with the book's title and author.

On PC:

  1. Find a cover image in the search results
  2. Right-click → "Copy image address"
  3. Paste the URL into the cover image field

On Mobile:

  1. Find a cover image in the search results
  2. Long-press → Select "Download image" or "Save image"
  3. Return to Reading Forest and tap the button
  4. Tap "Choose from files"
  5. Select the saved image to complete the setup
About URL pasting on mobile
Many mobile browsers don't show a "Copy image address" option, so we recommend downloading the image and using the button to set it.
External URLs may become broken links
External image URLs can stop working when the server removes or blocks the image. To keep images reliably, save them to your device and use the button.

Enter URL Directly

You can also type or paste a URL directly into the cover image field. If the image cannot be loaded, an error message with guidance will be shown.

Automatic Broken Link Detection

When a file is opened, external URL cover images are checked in the background. If broken links are found, a toast notification lets you search for replacements or remove the broken URLs.

Automatic upload of local images
Cover images saved locally on PC are automatically uploaded to Google Drive when saving the rfnote to Drive. No extra action needed.

For detailed instructions, see the Cover Image Guide.
